EXGESS-REGISTERING METER. v

Application filed ctober 30, 1923. Serial No. 671,817.

To all 'w71 om t may concern:

Be it known that I, OT'ro TEMPERLI, a citizen of the Swiss Confederation, residing at Zug,fCa1iton Zug, Switzerland,`have made a newV and useful Invention Relating to an Excess-Registering Meter, of which the followin scription.`

It has been proposed to provide excess registering meters, especially those for use with electricity meters, which show on a dialthe maximum demand during a given interval of time, with analarm device, in

orderto draw the attention of the consumer to the fact that the predetermined limit of current consumption is being exceeded. If the alarm is notobserved, or if no means are available to reduce the excess consumption at once, heavy expenses are incurred, as, with the prevailing` tariff systems, the consumer must then pay for allthe energy consumed in the interval between two meter readings at the higher rate corresponding to the maximum consumption ever reached, i. e. in this must also pay at the higher rate for energy taken when his demand was below the maximum limit set. As the time during` which an excess of current is taken is, in most cases, very short, and as the average load is generally far below said maximum amount, the said manner of charging is unjust to the consumer.

The object of the present invention is to provide means by which it is possible to charge for the quantity oflenergy actually used in excess of the maximum demand limit. This object is attained b the use of a tariff counter which is thrown into gear with the driving element of the meter as soon as the demand mined limit.

One method of construction is shown diagrammatically in the drawings, in which Figure 1 is an elevation of an excess registering` meter constructed and arranged in accordance with my invention, with parts removed.

Figure 2 is a .vertical sectional view of the same on the plane indicated by the line 2-2 of Figure 1. p

On the spindle 2 of a. Fer meter 1 is fixed a disc 3, ruiming between the pressure coil 4 and the current coil 5 of the iron core 6 well known in electricity meters of the Ferraris type and therefore raris electricity g is a full, clear, and exact de-f exceeds the predeternot particularly described. In the meter a double-tariif-counter 7 is arranged having two integrating trains 8,9. The spindle 2 is provided withy a. wormV 11 which drives'a transverse spindle which is rotatably and movably arranged. The free end 10 of the spindle 10 is linked to the armature 16 of an electromagnet 15; moreover a spur wheel 12 is fastened on this spindle 1() which can be brought into lmesh with either of two spur wheels 13, 14 driving the integrating trainsV 8, p 9 registering the energy consumed. Moreover, the spindle 2 is provided with a worm 17 which drives a shaft 18 bymeans of worm wheel pinion. p Onspindle 18 a pinion 19 is fixed meshingl with a spur wheel 45 fixed to aspindle 42. The latter is linked at one end to the armature 48`of an electromagnet 44, to the other end a pinion 41 is fixed engaging a toothed gear 86. The gear 36 is fastenedto shaft 85 bearing a pointer 87 over a scale 20'fixed `to themeter casing by brackets 21. The said pointer is a maximum demand pointer. 'The' shaft 42 is rotatably and inovably lmounted and may be uncoupled from the meter spindle 2V lby means of the electro-magnet 44 working in conjunction with the armature 43 linked to theshaft 42. The'maximum demand pointer 37 works on an arm 23 adjustably arranged on a sleeve 22 fixed to the scale 20 concentrically with axis 85. `The arm 23 may be fixed by means of a nut 24 at any convenient position. The said switch comprises a `double-armed spring actuated lever 25 pivoted on a pin 27 on said arm 23. One armof said lever 25 is bifurcated, the other arm plays between two stoppins 2,6 fixed on arm 28. A spring 28 tends to press said lever 25 on either of said stops 26. The free end of lever25 is provided with a pin`29 which actuates a blade spring 8O carryingone conf tact piece which works in conjunctionV with a contact piece Bliixed to arm28.V .Said spring 80 when resting on the Vfixed piece 31 closes the circuit 33 through the electromagnet 15 which is connected in parallel with the pressure coil 4, in the shunt circuit of the meter 1. The circuit of the electromagnet 44 is opened and closed by means of a clockwork or time switch of any well known type as used with maximum demand indicators, and not shown in the drawing.V

The shaft is rotatably mounted in a boss 34 of the casing 1, it carries the toothed gear 36 and the maximum demand pointer 37. The pointer 37 is provided with a pin 38 which cooperates with the bifurcated yarm ot lever 25. A spiral spring 39 iixed with one end to a lug 40 on said boss 34 and with the other to the gear 36 tends to return the pointer 37 to its initial or Zero position with reference to scale 20 after the pointer has been set by the driving elements of the meter. V* The gear 36 is driven bythe pinion 41 as long as the gears 45 yand 1'9 are in mesh, but as soon as electromagnet 44 attracts, the armautre 43 the gears 1.9, 45 are disengaged and pointer 37 is tree to follow the spring 39a As ,long asthe pointer 37 driven by the gearsv 17, 19, 45, 41 and 36 and by the drivingelements 3, 4, 5 of the meter does not pass the maximum determined by `the position given to arm 23 the electromagnet 15 is 30, 31 being open.-

not excited, the switch The spur gear 12 engages pinion 14` and the energy consumed is recorded on the lower counter-9.

If `the maximum ,dem-and pointer 37 reaches the limit set, its pin 38 strikes againstone prongof the biiurcated arm ci lever 25. The latter takesA part in the movement of the pointer 37, and the spring 28 acting on the lever tilts the latter so that it assumes its end position and abuts against they second stop 2,6.. The spring'- 30 is released and the-switch 30, 31 is closed. The circuit oi Vthe electro-magnet 15 is Vnow closed, the armature 16 is attracted and the mand.

gear 12 on the spindle lO is thrown intogear with the pinion 13 and the upper counter 8 rectnYds new the venergy consumed in excess of thev predetermined vmaximum de- At the end ot the recording period, current passes through electromagnet 44 its armature 43 disengages the gears 45 and 19 and the; pointer 37 is returned to its zero position by the spring 39. Upon returning to its 'Zero position, the pointer 37 strikes against thesecond prong ot the biffucrated arm 25 :and thereby tilts over the lever 25 into its initial position by means oft spring 39; The circuit oi the electro-magnet 15 is now broken at 30, 31 andthe spindle 10 dro-ps, thus coupling the counter 9 with the spindle 2.l In this manner ya rapid changeover is effected. f

The energy recorded on the counter 9 is charged at a lower rate and' tl'la't' recorded by counter 8 at a higher tariH and the consumer has only to pay the high tariii for that energy which he actually consumed in excessy of the limit determined by the position 0i arm 23.

Havingy now described my invention and in what manner the same is to be preformed, whatI claim is 1. In an excess registering meter a spindle mounted for rotation,l an element thereon, a corefhavin-g a pressure coil and a current coil between which the said element is arranged, a pair of counter mechanisms, means to, alternately operate saidcounter mechanisms including a shittabl'e element, a maximum time pointer, a spring to return the pointer to initial position, means including ashiitable element connecting said spindle to said pointer to cause the latter "tobe mevedk by the spindle, electrically operated. means to control the last named shiftable element, electrically operated means to centrolr lthe Vfirst named shiftable element and included in open circuit with the pressure coil, and a switch arranged for operation by the said pointer to close said circuit when said pointer reaches a predetermined position.
